What you should know
Seasonal flooding risks: Several campgrounds in the area are susceptible to flooding.

A few of the campsites will flood, not bad enough to get to your camper, but just enough to be annoying."
Noise considerations: Urban campgrounds often have noise from nearby transportation. At Casino Queen RV Park, "There is train noise but we couldn't hear it with the air conditioners running," reports a visitor. Another adds, "You can hear trains occasionally as well as the METRA rail."
Limited shade at newer parks: Many RV parks near St. Peters are relatively new and lack mature trees. "The grounds are clean and pleasant, if a bit sparse with little shade. This will change over the subsequent years, however, as there are many relatively newly planted trees," notes a camper at 370 Lakeside Park.
Tips for camping with families

Tips from RVers
Utility placement variations: RVers should be aware of unique utility setups at some parks. At Casino Queen RV Park, "Utilities are set up weird on all sites - Water and electric are at the very rear of the site by the sewer, so you will need a decent sized hose to reach if your water intake is in the front of your camper."
Wi-Fi reliability: Internet connectivity varies significantly between RV parks. At Covered Bridge RV Park, "The wi-fi was surprisingly good enough that my wife and I could both work off of it and even stream shows on the Roku the whole week," though they noted connectivity issues on their final day.
Gate code systems: Several RV parks near St. Peters use automated gate systems. "The park is not staffed, you get a gate code in your email to access the park," mentions a Casino Queen RV Park visitor, highlighting the importance of making reservations in advance to receive necessary access information.
